Optimisation of video-data transmission in telematic system

Abstract

The goal of this paper is to analyse, define, and summarise the requirements on networks connecting telematic technologies based on Intelligent Transport Systems (ITS). The paper describes the methodics of setting and a general concept of technological networks interface based on available and applicable standards Focus is set on optimisation of data transmission in the form of a video-stream and its tunnelling through xDSL transmission technology. The implementation of the designed compression algorithm and interface between open and technological-type networks is described. The summary describes a proposed subjective method for quality evaluation of transmitted video-flow for the needs of telematics supervision systems dispatchers.
